# --description--
|
||
|
|
||
|
フォントサイズは次のように `font-size` という CSS プロパティで制御されます:
|
||
|
|
||
|
```css
|
||
|
h1 {
|
||
|
font-size: 30px;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
# --instructions--
|
||
|
|
||
|
`red-text` クラスがあるのと同じ `<style>` タグの中に `p` 要素の項目を追加し、`font-size` を 16 ピクセル (`16px`) に設定してください。
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
`style` タグの中で `p` 要素の `font-size` を `16px` に設定してください。 ブラウザとテキストのズーム設定は 100% にする必要があります。
|
||
|
|
||
|
```js
|
||
|
assert(code.match(/p\s*{\s*font-size\s*:\s*16\s*px\s*;\s*}/i));
|
||
|
```
|
